GRAVES experimentation with GNU Radio

Station : Biconal antenna with HackRF One and GNU Radio

View moon between -220 and -240 Hz
View plane between -100 and 100 Hz

Can be used to define satellite orbits with a more sensitive station


Hey @michel, this is super interesting!

A couple of people in our community have tried this approach before and interestingly it yields some nice results and potentially valuable SSA information.

Can I ask your approximate location?

That could be improved and more specific to the frequency observed I guess.

That is also a big area that could be improved. I would argue that a rtl-sdr v3 with a nice LNA and filter could be better that your current reception setup.

Speed ​​calculation (simplified Doppler) of the planes received this morning using a Slim-Jim antenna, an SDR key and GNU Radio based on flowgraphs from satnogs.
